[A case of cryptococcal retinochoroiditis associated with acquired immunodeficiency syndrome]

A case of cryptococcal retinochoroiditis associated with acquired immunodeficiency syndrome (AIDS) is reported. The patient was a 22-year-old man with hemophilia A. He was found seropositive for human immunodeficiency virus three years ago. He was admitted with complaints of fever and cough. CD4/CD8 ratio was 0.01 and CD4 lymphocyte count was 10/mm3. Two weeks later, ophthalmological examination revealed some yellowish white focal lesions at the posterior fundus. More detailed examinations were impossible because of his poor general condition. He died one month later. The autopsy showed disseminated cryptococcosis. Ocular histopathological examination revealed cryptococcal retinochoroiditis without any inflammatory reaction. This is the first report in Japan of this disease associated with AIDS and of a histopathological study of it.
